This seems entirely reasonable to me. And to people complaining that this is censorship, it is absolutely not. You can still type these words just fine, it's just not going to interpret swipes that are inherently probabilistic and often ambiguous as potentially risky terms.

This seems like a feature, because I swipe all the time and send messages without realizing I got a word wrong, especially because the word it chooses is usually with the same first letter and approximately same length.

All this is doing is avoiding high-risk words and terms, and making you type them out letter by letter to ensure you aren't sending an accidentally sexual/swear/political message to your Mom/boss/colleague.

This would be problematic and censorship if it were preventing you from typing the phrases at all. It's clearly a helpful feature, however, to prevent you from accidentally typing risky phrases when using something as error-prone as swipe typing.

"imessage isn't working"? really?
